SS 904L Needle Valves

We believe in providing the right quality, at the right time and in the right place. Instinox is the most popular Indian manufacturers and suppliers of all grades of stainless steel ss 904l needle valves. Our products are available for immediate delivery as soon as the purchase order is received. We have an inimitable, coordinated process right from the production till the logistics department. We have our merchandisers, all around the world who have played a great part in making us what we are today. We are serving since two decades, and this does not look forward to stopping anytime soon.

A ss 904l needle valves manufacturers  uses a tapered (reduce in thickness towards one end) pin to slowly open up space for subtle control of flow. The flow can be controlled and regulated with the use of a spindle (a slender rounded rod with tapered ends). A spindle is something which works in a round motion used for controlling the flow. Stainless steel 904l needle valve has a comparatively small opening with a long, tapered seat, and a needle-shaped plunger (part of a device or mechanism that works with a plunging) on the end of a screw, which exactly fits the seat. As soon as the screw is turned and the plunger retracts, flow is possible between the seat and the plunger, however, until the plunger is completely retracted, the fluid flow is significantly impeded. Since it takes many spins of the fine threaded screw to retract the plunger, precise regulation of the flow rate is possible.
The virtue of the needle valve is from the vernier (a vernier scale is a device that lets the user measure more precisely than it could be done unaided when reading a circular measurement scale) effect of the ratio between the needle’s length and its diameter, or the difference in diameter between needle and seat. A long travel axially (control input) makes for a very small and significant change radially (affecting the resultant flow).Needle valves may also be used in vacuum cleaner systems, when a specific control of gas flow is required, at low pressure, such as gas filled vacuum tubes, gas lasers and similar devices. We are our merchandisers, who have helped us in gaining the advantage and a trusted name in the whole industry. Here, you just place the order, and we are there to look after the rest.

SS 904l needle valves suppliers, having the unique properties, are mostly considered in chemical industries. Applications in which consistent and limited flow are required do require needle valves for their successful completion. Stainless steel 904l Needle valves are used especially when a consistent, measured, low flow rate must be upheld for some time, such as the stagnant fuel flow in a carburettor. Needle valves are used in changing the direction of the flow.
Take to mind that the float valve of a carburettor (controls the fuel level within the carburettor) is not a needle valve, although it is described as one. It uses a blunt conical needle, but it seats against a square edged seat rather than a matching cone. The aim here is to obtain a well-defined set between two narrow joining surfaces, giving firm shutoff of the outflow from only a light float pressure. Since flow rates are less and many bends of the valve stem are required to fully open or close, needle valves are not used for simple shutoff applications.
The force advantage of the fine threaded stem is more since the opening is narrow, Needle valves are usually easy to shut off completely, with solely finger tight pressure. The spindle of a needle valve made from brass, when shutting off the flow can be easily damaged by extra turning force. Small simple needle valves are often used as bleed valves (hydraulic valves that combine one or more block/isolate valves,) in water heating applications. It is not easy to tell from examining the handle position and check whether the valve is open or closed, unlike a ball valve or valves with a resting stem.

We believe that a twenty-foot long path cannot be covered in just two ten foot jumps, it takes a step-by-step process, to make it the best one. Our team is always inclined towards it. We are an ISO certified firm, and we have also fulfilled other industry requirements. We have followed the best practices in manufacturing till date. Due to our high-quality standards, we have an overwhelming record of less than one percent rejection rate. We follow a hundred percent in house checking of goods, before taking it any further. High quality, defect free products using technology at its maximum, is surely a thing not indulged into by anyone from the whole industry.
